Title: Non-contact type measuring apparatus
Inventor: DANIERU GUIDOTSUTEI
IPC: G01N21/55
Filed: 1988-08-19
Abstract: PURPOSE: To determine the change in the reflection factor and transmittance of a sample accurately without being affected by the fluctuation of a light source, by adjusting the polarization direction of incident rays until the quantity of light of beams through the sample is equal to that of other beams. CONSTITUTION: A light source 1 is polarized linearly by a polarizer 2 so that the direction of the electric field of emitted rays is at a constant angle to the light axis of a polarization sensing beam splitter and a prism 3. The two cross polarization rays move toward a reflector 4 and a sample to be measured and the reflection rays move toward photo detectors 5 and 6. Photo current from the detectors 5 and 6 is inputted to a balanced circuit 7, a differential signal is inputted to a feedback loop 9 via an amplifier 8, and a polarizer 2 is rotated so that the differential signal is always at zero level.

Title: Light-emitting device
Inventor: GOTO MASAO
IPC: H01J17/49
Filed: 1992-07-31
Abstract: PURPOSE:To improve the light-emitting brightness of a light-emitting device for emitting light with a fluorescent film excited by electron beams or ultra-violet rays produced in a vacuum space or discharge gas space, and also improve the operational efficiency thereof. CONSTITUTION:When electron beams generated from a cold cathode 3 with field emission are applied to a fluorescent film 7 provided through a conductive film 17 on an insulating base board 6 to excite the fluorescent film for the emission of light or when the fluorescent film is emitting afterglow, d.c. voltage is applied between the conductive film 17 and a film electrode 8. In the type of a plasma display panel provided with a fluorescent film, when ultra-violet rays are applied to the fluorescent film or when the fluorescent body is emitting afterglow, d.c. voltage is applied between two conductive film holding the fluoresent film therebetween. Thereby, Gudden-Pohl effect is produced in the fluorescent film, so that light emitting brightness and operational efficiency may be increased as compared with those when a fluorescent film is excited by only ultra-violet rays for the emission of light.

Title: Disk cartridge
Inventor: YOSHII TETSUJI
IPC: G11B23/023
Filed: 1988-08-18
Abstract: PURPOSE:To store and hold to kinds of large and small disks with the optimum force respectively by providing a holding arm which is supported rotatably nearby an opening part and a curved arm shaped energizing means which energizes the holding arm. CONSTITUTION:The arm part of a holding arm spring 23 is curved almost in a dog-leg shape. Consequently, while a point in front of or behind the maximum displacement point of the holding arm 21 in storing a standard disk, i.e. the maximum part of the standard disk 4 passes the free end of the arm 21, the arm is applied with a spring force from a curved part close to the fulcrum of the spring 23 to a point distant from the support shaft 22 of an arm 21. Therefore, a rotating force which is much larger than the force in the process of the displacement is applied. Thus, the large rotating force is generated by the simple constitution and nor only the small-sized disk, but also the standard disk can securely be loaded and held with the large force.

Filed: 1989-08-08
Abstract: PURPOSE:To prevent a coloring phenomenon in a sensitive achromatic color part by a method wherein the I/O conversion characteristics of a non-linear arithmetic circuit conducting a non-linear arithmetic processing to each color signal are compared with the most desirable I/O conversion characteristics in a non-linear operation to a chromatic color signal, and a non-linear arithmetic circuit having the I/O conversion characteristics of indicating a small output signal level to a part of a low signal level is used. CONSTITUTION:Each of non-linear arithmetic circuits 2 - 5 is provided with four look-up tables, which independently apply a non-linear conversion to inputted color signals Rc, Gc, Bc and base color signal K. The most desirable I/O conversion characteristics in the look-up tables are different from I/O conversion characteristics in the look-up tables in use. Each of the non-linear arithmetic circuits 2 - 5 separately applies a predetermined non-linear conversion to inputted color signals Rc, Gc, Bc and base color signal K. The respective output signals from the non-linear arithmetic circuit 2 are added to each other by an adder 6 to be outputted as a Red signal R'. Similarly, a Green signal G' and a Blue signal B' are outputted. The respective output signals from the non-linear arithmetic circuit 9 are added to each other by an adder 9 to be outputted as a base color signal K'.

Filed: 1987-08-19
Abstract: PURPOSE:To obtain a water-base ink composition which has excellent ejection characteristics, is free from clogging and, in particular, gives a printed image with excellent definition, water resistance, and light resistance, by incorporating a specified water-soluble dye into a water-base ink.

Title: Servo controller
Inventor: IWASHITA HEISUKE
IPC: G05D3/00
Filed: 1988-08-18
Abstract: PURPOSE:To perform the smooth control of the acceleration value and to evade the discontinuousness of the surfaces cut with the numerical control by using a backlash acceleration control means to calculates the backlash acceleration value which is gradually reduced and controlling the speed of a servo motor. CONSTITUTION:The position error is monitored by a position error arithmetic part 12 and an error counter 13, and the inversion of the revolving direction of an amplifier motor 18 of a servo motor is detected when the contents of the counter 13 are equal to zero. A backlash correction timing deciding part 19 outputs the backlash correction value BC received from a numerical control part 11 and at the same time applies a direction inverting signal RDI to a backlash acceleration value control part 21. Then the acceleration value which is gradually reduced in terms of the exponential function is calculated after the acceleration is started via a backlash acceleration value arithmetic part 21b, etc., and added to a speed command VCMD. Thus the backlash is smoothly corrected so that the projection of quadrant caused by the shortage of acceleration value at the start of acceleration is avoided. At the same time, the inside cut-in due to the excessive acceleration value at the end of acceleration is evaded. Thus no discontinuousness is caused to the surfaces cut with the numerical control.
